Application filed July 26,

The present invention relates to improvements in wheel removers, and hasfor an object to provide an improved wheel remover in a which simplicityand strength of construction are combined With ease of application andoperation.

Another object of the invention is to provide a device of this characterexercising great pulling effort through mechanical operation withoutimposing burdensome'work upon the operator. i v

A further object of the invention resides in providing an improved wheelremover in which the application of force is direct and equalized andfreefrom lateral strain.

With the foregoing and other objects in view, the invention will be morefully described hereinafter, and will be more particularly pointed outin the claims appended hereto.

In the drawings, wherein like symbols refer to like or correspondingparts throughout the several views,

Figure 1 is a top plan View of'the device, with parts broken away andshowing the same applied to a felly of a wheel to be removed.

Figure 2 is a section taken on the line 22 in Figure 3. j

Figure 3 is an enlarged fragmentary plan View of the device shown in aposition subsequent to Figure 1. r v

Figure 4 is a section taken on the line 4-4 in Figure 3 with the leversand gear segments removed, and

Figure 5 is a perspective view of one of the claw arms.

Referring more particularly to the drawings 6 designates a plungershaped at one end with a nose 7 for taking against the end of an axle 8represented in Figure 1. The other end of the plunger 6 is provided withan en larged and heavy head 9- positioned freely of other parts so as toreceive blows from a hammer when necessary. Opposed rack teeth 10 and 11are formed upon opposite longitudinal side edges of the rack bar 6 fromadjacent the head 9 thereof along a maximum length thereof.

As shown in Figure 3, the plunger 6 is slidablymounted between framebars 12 and 13 which are provided with the opposed internally projectingribs 14 and 15 for taking into the longitudinal grooves 16 and 17 in theupper and lower edges of the plunger. The ribs and grooves arepreferably wedge-shaped in form with truncated apexes, giving the claws28 and 29 for 1928. "Serial No. 295,552.,

plunger 6 the cross sectional form of an H. By reason of this form theplunger 6 is reinforced and strengthened by the flanges, and connectingweb and at the same time the plunger is guided in a true rectilinearpath.

Gear sectors 18 and 19 are positioned'to mesh with the rack teeth 10 and11 respectively, these sectors being mounted upon levers '20 and 21which are fulcrumed on pins 22 and 23 mounted in the frame bars orplates. Alining openings 24 and25'are provided in the upper and lowerplates 12 and 13 toreceive the bolts or pins 22and 7 As shown moreparticularly in Figure 2," the ends of the plates 12 and 13 arebifurcated to receive the claw arms 26 and 27 having the grasping therim of the felly 30 or other the like.

Each claw arm 26 as shown in Figure 5, is provided with a pair of spacedshanks 31 and 32. Each shank is provided with a row of perforations 33,34, corresponding perfora t'ions being in axial alinement to receive thepins or bolts 35 and 36 by which the claw arms are pivotally securedtotheframebars 12 and 13. The ends of the frame bar 12 are provided withthe perforations 37 andl38; while; the end portions of the companionframe bar 13 are formed with rows of part of the wheel, pulley orperforations 39 and 40. Extension pieces 41 and 42 are carried by thebar' 12 and I extend inspaced relation outwardly beyond and insubstantial parallelism with'the p'er-. forated end portions 37and 38.These extension piecesare open at their upper and lower edges and attheir outer ends and receive between the same and the perforated 6 endportions of the framebar, the shanks 31. i

The extension pieces are provided with the rows of perforations 43 and44, corresponding with the rows of perforations 37 and 38 in order toadjustably receivethe pins 35 and 36 whereby the pivotal points of theclaw arms, and incidentally the claw arms themselves, may be setinwardly or outwardly' of the frame. By selecting the perforations 33and 34 through which'the pins 35 and 36 i may be passed, the claw armsmay be either' shortened or lengthened.

In a similar way perforated extension pieces 45 and '46 are carried bythe lower side of the lower frame bar 13 and receive therebetweenthelower shanks 32 of the claw arms.

V In the operation of the device, the levers 20 and 21 are initially ina spread condition, as indicated in Figure 1, although they may be morewidelyspread. In this condition of the parts, the nose 7 of theplungerfi is applied to the end of the axle 8 so that the axis of theplunger and the axis of the axle extend in alinement. The claws 28and 29are then applied to the part to be removed, for instance tothe rimBO, byswinging the claw arms 26 and .27 upon the fulcrum points35 and 36.'

'Theparts are now in condition for operation, I v which is accomplishedby moving the levers and 21 together as indicated in Figure 3.

This movement of squeezing the levers together isaccompanied by apartial rotation of the gear'sectors 18 and 19, which, meshing with therack teeth 10, and 11, serve to move thefra'me' outwardly along theplunger 6, the

plunger being held against movement by its engagement with the axle 6.The shifting of the frame outwardly upon the plunger will 4 beaccompanied by a pull upon the arms 26 and27 and these arms will drawwith them the wheel 30, pulley or whatever they may be attached to. Incase the parts stick or a great resistance'is interposed to the movementof 7 the levers 20 and 21 together, the head 9 of the plunger may besubjected to blows from a hammer. 1 fIt will be noted that the presenceof the gear sectors upon opposite sides of the double rack plunger 6have aycompensating and equalizing effect whereby the operating force iscentralized along the axis of the plunger. The arrangement avoidspossibility of unequal pressures at opposite sides of the rack bar. andprevents the shifting of the device laterally which would throw the rackbar out of line withthe axle and impose unnecessary strainsupon thehooks or claws and other parts. By'the use of the device the thrust isept'ina truerectilinear path and as a consequence ease of manipulationis secured to ahigh degree.

It is obvious that various changes and modificatio'ns may be made in thedetails of construction and design-of the above specifically describedembodiment of this invention without departing from the spirit thereof,

such changes and modifications being restricted only by the scope of thefollowing claims. v c

What is claimed is 1-- 1. An improved wheel remover comprising a framecomposed of spaced bars having end portions provided with rows ofperforations,

extension pieces on the ends of the bars having rows 'of perforationstherein, claw arms having spaced shanks for fitting between the ends ofthe bars and the respective extension pieces,

pins passing through the bars, extension pieces and said shanks, meanscarried by the frame for engaging an axle, and means also carried by theframe for cooperating with the first named means to move the frame andclaw arms outwardly from the axle.

2. An improved wheel remover comprising spaced bars having perforatedends and perforated extension pieces outwardly of said plunger andhaving toothed sectors meshing with the opposite rack teeth. I

In testimony whereof I aflix'my signature.
